Ok, here we go Wax.
I don't add split rings to the nose of any treble bait, but I use a "speed Clip". It's kinda like a fancy snap. I have noticed no I'll effects on the action of the baits and it dies allow me to swap the out quicky. If I know I will only use that bait and have use for anything else I'll just tie directly.
Now I Love to mod my baits and change the split rings to the trebles and change the trebles to larger or smaller and different brands. That no dought changes the action and feel of the bait but that the intent.
By all means experiment. There is no hard fast rule in fishing other than the more time u spend on the water the more u learn. So do what u like, change what u think needs changeing and put it on the water and decide for ur self. That's the way u gain confidence in ur gear.
Good topic Wax.
